Comment Locks that resist bumping (Score 3, Informative) 454
I've been reading about this a bit lately and found an interesting paper on bumping locks at http://www.toool.nl/bumping.pdf
They also have a section on locks that resist bumping:
There are mechanisms that do not allow for the two pins to separate except when slid sideways, such as used in the Emhart interlocking lock (which is not being produced anymore). As far as we can see, such a mechanism would successfully foil the bumping attack. Also some mechanisms which have a one-piece locking mechanism (such as a 'sidebar') may resist bumping. Locks that involve rotating discs (such as Abloy Protec) or magnets (such as Evva MCS and Anker) are also not susceptible to this attack. Klaus Noch sells modified standard Euro profile locks which lock up (i.e. 'broken but closed') upon most attempted manipulations, including bumping.
I found the Abloy Protec lock (with rotating discs) especially interesting and I'm going to get this for my own front door when I get the chance. On the same website they have an paper on the Abloy Protec as well: http://www.toool.nl/abloypart3.pdf
